A filing for the DWS Tax Exempt Portfolio - Service Shares tells us, "Upon the recommendation of DWS Investment Management Americas, Inc. (​the '​Advisor'), the investment advisor for DWS Tax-​Exempt Portfolio (​the '​Fund'), the Board of Trustees of Cash Account Trust has authorized, on behalf of the Fund, the termination and liquidation of Service Shares, a share class of the Fund (​the '​Class'), which will be effective on or about November 25, 2025 (​the '​Liquidation Date'). Accordingly, the Fund will redeem all outstanding Class shares on the Liquidation Date. The costs of the liquidation, including the notification to shareholders, will be borne by the Fund but reimbursed by the Advisor, after taking into account applicable voluntary or contractual expense caps then in effect by the Advisor to waive or reimburse certain operating expenses of the Fund." It explains, "Shareholders who elect to redeem their Class shares prior to the Liquidation Date will receive the net asset value per share (​normally, $​1.​00) on such redemption date for all Class shares they redeem. Shareholders whose Class shares are redeemed automatically on the Liquidation Date will receive the net asset value per share (​normally, $​1.​00) for all Class shares they own on the Liquidation Date."
